SQRT Square Root of an Array

Usage

Computes the square root of the argument matrix. The general syntax for its use is

   y = sqrt(x)

where x is an N-dimensional numerical array.

Example

Here are some examples of using sqrt

--> sqrt(9)
ans = 
  <double>  - size: [1 1]
    3.000000000000000      
--> sqrt(i)
ans = 
  <complex>  - size: [1 1]
    0.70710677        0.70710677    i  
--> sqrt(-1)
ans = 
  <dcomplex>  - size: [1 1]
    6.12303176911189e-17     1.000000000000000    i  
--> x = rand(4)
x = 
  <double>  - size: [4 4]
